To aZZ whom, it may concern.-

Be it known that I, ALBERT F. PRESTON, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Vamp Marking Maohines for Boots or Shoes, of which the following is a full, clear, and exact description.

This invention consists of an apparatus suitably constructed and arranged to mark and indicate on a vamp for a boot or shoe the places where to stitch on the quarters and the toe tips, and the center line of the vamp for the proper location of the quarter-seam, all at one operation, all substantially as hereinafter fully described, reference being had to the accent panying plate of drawings, in which Figure 1 is aplan View. Fig. 2 isaside View. Fig. 3 is a plan view below line 3 3, Fig. 2; and Fig. 4 is a plan view of the under side of the working parts of the apparatus; Fig. 5, a partial side view and partial vertical sectional view on line 5 5, Fig. 1; Fig. 6, a plan view of a vamp, as marked by the present apparatus.

Fig. 7 is a detail cross-section on line 7 7, Fig.

1. Fig. 8 is a detail crosssection on line 8 8, Fig. 3; Fig. 9, a detail plan view. Fig. 10 is a detail plan and partial sectional view, and Fig. 11 is a detail sectional view.

In the drawings, A represents a table or bed, to which is hinged the bar B, at a, for it to swing up on such hinge, as shown, for instance, in Fig. 2 in side view.

C is a transverse rib or bar secured to the bed-plate A, and having at each end a block, D, secured to the bed A, through which extends the right and left hand screw E, arranged to freely turn in said blocks, but prevented from moving longitudinally by shoulders b, and a central block, F, secured to the plate, and having amilled middle head, (Z, for opera tion thereof.

G H are two arms, each having atransverse groove, e, on its under side, fitting over the rib G, one, H, on the right-hand screw portion, J, and the other, G, on the left-hand screw portion, K, of the screw E, and each having a corresponding screw-thread to engage with its respective screw, their ends f projecting toward the front end of the bed-plate and resting thereon.

Turning the screw E by its head to the right or left correspondingly moves the arms G H toward or from each other, the distance from each other being limited by the blocks D, the arms being arranged to slide freely along the rib O and over the plate A.

L M are two arms between the guide-arms- G H, each screwing on to its respective screw K J, and by the turning of which they will move toward and from each other, and with the movements of the guide-arms, each being screwed onto its screw, so as to be close to its respective guide-arm, as shown in Figs. 1 and 3 in plan View.

The rear end, 9, of each arm L M extends back, as shown in the drawings, and bends upward slightly, so that each arm can swing vertically on its screw as a pivot, a certain distance for the end h to be, when in its normal position, away from or above the bed-plate, a short distance, as shown in side view in Fig. 2 more particularly.

The bar B has a central cross-bar, N, rigidly secured to it, extending each side thereof, and is so located on the bar that when the bar is swung down upon the plate the cross-bar will by its ends strike on the upper side of the ends h of the arms L M, and press such ends down upon the table, the arms swinging on their respective screws as pivots, and when the bar is swung up the arms will return to their positions (shown in Fig. 2) from the weight of the outer ends, 9, of such arms.

P is a cross-arm on the under side of the bar B, and fitting over the same by a transverse groove on its upper side, and in such manner that it can freely move back and forth along such bar.

' Q is a screw freely turning in blocks R R on the bar B, but prevented from longitudinal movement along the bar, the screw passing through the crossbar P, its screw-thread engaging with a screw-thread in the cross-bar P, so that turning the screw Q to the right will move said cross-bar toward the end a of the bar, and to the left said bar in the reverse direction.

S is another screw parallel to the screw Q, adapted to freely turn in the blocks R, but so as not to move longitudinally therein, and passing through, engaging by its screw-thread with a screw-thread in a block, T, arranged to slide on the under side of the bar B. Turning the screw S to the right will cause the block T to move toward the outer end of the bar B, and to the left in the reverse direction.

The screw Q, passes through an opening, a, in this block T, but allows it to move freely thereon.

Pivoted to and on the under side of the bar B at q is a flat strip, U, which by one end is pivoted at r to the end of another strip or bar, V, pivoted by its end to a block, W, adapted to slide back and forth in a longitudinal groove, t, in the bar B, having a thumb-screw, a, on the upper side of the barB, screwing into the block W, and arranged to secure said block firmly at any point along said groove.

The strip or bar U extends to and beyond the cross-arm P, and is arranged to lie and freely slidelaterally within aho'rizontalgroove, o, in the portion w of the cross-arm. The center of the pivot g on which this strip turns is in the same vertical plane as the front edge, 3 of the transverse rib 0. (See Fig. 11.)

On the strip U at z is marked a scale representing the different sizes of boots and shoes according to their lengths, from 5s childrens boots or shoes at a to 12s mens boots and shoes at b, and in the strip is a scale of holes, d, which are arranged on the strip in line with and from the pivot q, and are marked by the letters of the alphabet, as shown.

On the under side of the end h of each arm L M is a narrow rib, e, extending across the face, as shown in Fig. more particularly, and on the under side of the block T is a crossrib, f and another rib, g, crossing it, as shown in Fig. 9. The cross-arm l? is cut away, as shown in Figs. 2 and 5, more particularly at h, making a thin under edge at its front side, as shown in said figures. These several ribs e f 2 g and edges h are sufficiently thin that,if pressed firmly upon a piece of leather or a similar material ,they will leave corresponding indentations or impressions, but are not sharp enoughto cut or mar the surface of the leather.

The operation of the apparatus is substantially as follows: First,cut the vamp Y, which is shown in plan view in Figs. 1, 3, and 6, to the size and shape desired in any of the usual ways, and having raised the bar B into the position shown in Fig. 2, lay the vamp on the table, its two ends, Z against the front side, y, of the cross-rib C and between the two guide-arms G H, and then turn the screw E until such arms touch the ends Z as shown in plan view in Fig. 3. Then set the thumbscrew block W along the groove t until its mark at coincides with the mark on the scale z, indicating the length of the boot or shoe for which the vamp is intended, which in the present case, say, is No. 5 of mens sizes, and fasten the thumb-screw at such place to prevent the block W moving, and then move the cross-bar P by its screw Q along the bar B until its edge h is over the place on the vamp where it is desired to place and secure the toetip. Now swing or let down the arm B and press the same firmly upon the vamp placed, as described, upon the table. When raising the arm, the vamp will be found marked, as shown in Fig. 6 at r", by the arm-edges h of the bar P, showing where the toe-tip is to be at tached, its edges being placed to such marks; at v s the center of the vamp, and at t by the ribs on the arms LM and block T, where the quarters are to be attached to the vamp. Having thus marked one vamp, other vamps of the same size on which it is desired to locate the toetips in the same position can be marked in the edge h of the cross-bar 1? in the strip U by its number, the apparatus can be set at anytime for the marking of other vamps the same.

To change the apparatus to mark another size of boot or shoe vamp, and keep the relative'proportions of the toe-tip mark to its length, unloosen the thumb-screw w and move the block W along its groove 15 until its mark at is opposite the desired size indicated on the scale 2, and then cause the cross-bar to move along the bar B by its screw until its front edge, h", is over and coincides with the same hole, as indicated by the letter that was used for the first vamp marked, and then the vamp, when placed in the apparatus, and the guidearms moved, as described, to suit itswidth, it necessary, will be marked for its toe-tip to be in the same relative position on the vamp for its size as compared with the first one. When the bar is raised the marking-ends h of the arms L' M are raised, from the plate by the weight of their rear ends, g, leaving the bedplate free to place avamp under them and against the rib in position to be marked.

In lieu of the arms L M returning to their normal position by gravity, as described, they can be operated by springs, &c., or in any suitable manner.

The marking-rib g on the under side of the block T is arranged the proper distance from the front edge or side a of the block for the marking of the quarter-seam, and the block is set by its screw for its front edge to be in line with the line 11 of the vamp, and its marking-rib f is arranged to be centrally between the guide-arms G H; also, the marking-ribs e on the under side of the arms L M, are arranged the proper distance from the front edge, y, of the rib for their proper marking.

The pivot of the strip U on the bar Band its connection with the thumb-screw block is so arranged that the distance between the pivot q and its pivot on the block W represents the length of a boot or shoe, and the distance from the pivot q to the front edge, h, of the crossbar 1? represents the length from the edge of the tip to the back edge of the vamp, so that when the cross-bar P is adjusted to the same letter on the strip U the relative proportions of these two distances will be the same for all sizes.

This apparatus can be made of any suitable material, although if the bed-plate is made of wood or similar material it can have a plate, Z, of metal secured on its upper side, as shown in the drawings, for a better surface on which to operate.

Any suitable marking devices can be used other than the ribs shown.

If desired, a spring can be arranged between the bed-plate and the bar B in such manner that it will hold the bar up in the position shown in Fig. 2 for the convenient insertion of a vamp to be marked and to return it automatically to such position after a vamp has been marked.

The block XV can be arranged to move back and forth on the bar B in other ways than sliding in a groove.

Having thus described my invention, what I claim is s 1. In avamp-nxarking machine, the combination, with a bed-plate, A, having pivoted thereto a bar, B, with a groove, t, and a scale,
